MACHINE FOR MANUFACTURING PAVING-FLAGS.

Specification of Letters Patent.

Patented Dec. 30, 1919'.

Application filed April 29, 1919. Serial No. 253,435.

To all whom it may concern:

Be it known that I, FREDERICK G. JORDAN, a citizen of the United States, residing at Cement, in the county of Stevens and State of Washington, have invented certain new and useful Improvements in Machines for Manufacturing Paving-Flags, of which the following is a specification.

This invention relates to the manufacture of paving slabs or flags, and pertains especially to a machine for producing such slabs or flags as disclosed in my application for patent filed February 28, 1919, Serial No. 279777, such flags being double faced finished and composed of reinforced cement and concrete having asphaltic inserts, as shown, for example, in Fig. 25 of the drawings of this application.

The prime object of the invention is to provide a. machine for the manufacture of artificial or composition paving and building slabs of various sizes as desired to which the machine may be adjusted and fixed for producing the same.

A further object of the invention is to provide a machine wherein certain essential parts may be contracted and expanded preparatory to making slabs or flags of various size, and wherein the finished slab or flag may be lifted and reversed by operating certain members of the machine, and then discharged from the machine.

A still further object of the invention is to provide a slab-weight compensating device for balancing theslabs during the manipulation in and until their discharge from the machine, and to furnish devices for holding said compensating device during certain of said slab manipulations.

An object still further of the invention to provide a telescoping slalrsuppor'ting truss having end trunnions connected with elevating and balancing devices for expeditiously lifting the slabs from a molding frame or bed and permitting the slabs to be manipulated in suspended position preparatcry to removing the finished slabs from the machine.

An object still further of the invention is to provide novel and peculiar mechanism for starting the finished slabs from a molding bed in cooperation with the balanced lifting device and the traveling slab supporting truss.

Various other objects, advantages and improved resultsare to be found in the machine as hereinafter fully described and shown in the accompanying drawings forming part of this application.

The same reference characters denote the same parts throughout the several views of the drawings.

In carrying out my invention, 1 preferably employ four corner supporting pillars as 1 fixed to or mounted on a suitable base plate as 2 and bind the pillars together at equal distances apart by rods 3 strapped as at l, to the posts 1, and having turn buckles 4 for adjusting the molding curb truly square and to keep the posts in desired position for a skeleton frame 5 which abuts against the post and has a pair of shafts 6 mounted thereon which are each provided with a pair of cams 7 and a gear 8 meshing with worms 9 on a shaft 10 which has a suitable crankhandled wheel 11. The molding bed 12 is supported in a curb or special frame on the pillars 1 and brackets 2 clamped to certain posts 22, at 22 so that the cams may engage the under side of said bed for initiating the raising movement of the bed, as will be hereinafter further explained. The four cams are arranged to raise the bed and its flag perfectly true and level.

Four tubular posts 13 are fixed to the base plate 2, and each post has the inner end of a tubular rod 14 secured thereto by means of a T-coupling 15, so that one pair of the rods project in opposite direction from and parallel with the other pair of rods. Two clusters of tubular posts 16 are slidably supported on the base plate 2, and are slidable on the rods 14 by means of T-couplings 17, and said posts 16 are clustered in two pairs within and by means of a band 18 secured at 19 to each post 16, and to a pair of similar posts 20 outside of the bands. The T-couplings 17 each form a securing socket for the lower end of tubular vertical stanchions 22 which have their upper end secured in T-couplings 23 connected in pairs by tubular connections 24, and said couplings 23 are slidable on upper tubular rods 25 corresponding with the lower rods 14, except that the upper rods are continuous so that there is only one pair of these rods to two pairs of the lower rods.

The stanchions 22 are assembled within and secured to a band 26 adjacent to the upper couplings 23, and an elbow brace 27 is connected with certain of the stanchions and the rods 25 by collars 28. Similar braces 29 are secured to the lower end of the stanchions by a collar 30, and these braces ride upon the base plate 2 in sliding movement for relative adjustment of the stanchions on the rods 14 and 25. The couplings 23 are provided with set bolts 31 for holding the stanchions in adjusted position on the rods 14 and 25,

and this adjustment is made according to the size of the slab or flag, for example as shown in Fig. 1 of the drawings, the stanchions may be adjusted for making a large slab as 32, and further adjusted for making a smaller slab as 33. Obviously there is a molding bed plate as 34 provided for slabs of each size, and insert designs 45 and the bed fit within a surrounding curb or frame 35 as for the slab 32, and a like smaller frame 36 as for the slab 33. These frames have angle corner braces 21, and securing brackets 37 for adj ustably securing the frame ends to the overhanging cap plate 38 0f the fixed or main supporting pillars 1, as more clearly shown in Fig. 32 of the drawings. The curb or supporting frames 35 and 36, which hold the molding bed, is vertically adjustable for flags or slabs of difierent thickness as shown in Figs. 1 and 22, by means of countersunk set bolts 39 adjustably connecting the brackets 37 with the post cap plates 38, and the curb or frame 36 is provided with gap plates 40 which close the openings 41 in the curb during the tamping of the slab material on the bed. Said openings afford passages for the neck 42 of a trunnion 43 on each end of a slab-supporting yoke 44 under the bed, and is raised with the slab and bed out of the curb, so that said passages are opened by the upward trunnion necks displacing the gap plates 40, which are more clearly shown in Fig. 20 of the drawings.

In order to temporarily retain the nonslipping inserts 45 on the bed plate 34 during tamping of flag mate-rial around the inserts, I provide said plate with pins 47 and in order to support a slab binding truss 48 elevated from the plate 34, I temporarily place blocks 49 on said plate at the intersection of the truss members so as to support the latter during the first tamping of flag material on the plate and around the truss. The blocks are finally removed from the flag and their cavities left in the flag are filled by the second tamping and trowel finished.

The trunnioned yoke 44 has telescoping parts adjustably secured by set bolts 50 for different size slabs or flags, and the trunnion bearings 51 are suspended by links 52 which are attached to cars 53 of the ends of telescoping lattice guides 54: having an eye 55 to which is attached one end of a lifting chain or cable 56' running over guide sheaves 57 journaled in bearings 58 adjustably secured on the upper rods 25, and the other end of said cables is anchored under a weight supporting disk 59 having a clamping member 60 fitting the stanchions 22, and adjustably locked to the latter by a clamping member 61. Disk weights 62 and 62 are employed to compensate the weight of the slab, its bed and curing frame, and to counterbalance the same during the operation of raising or lifting and suspending the slabs preparatory to finishing and discharging them from the machine. In order to lift a slab together with its bed and sup porting yoke it is first raised or given initial lifting out of the curb by the cams to the position for applying the track or rail 63 as shown in Fig. 5 of the drawings. This initial lift is necessary to raise the slab out of its frame or curb so as to permit the laying ,on of the curing frame.

The compensating weights are all slotted disks of different thicknesses, making it possible to easily adjust the counterbalancing weight of any size of flag, which is done when making the first flag of any size. When once adjusted the weights remain in position, and undisturbed, as long as the same size and thickness of flag is being manufactured. Then the compensating weights receive the same and raise it to the reversing position, reverse and lower it to the discharging position, where and when (only) the clamps 60 and 61 are screwed tight, the bed-plate then alone raised, counterbalanced by its own compensating weights, as shown in Fig. 5, the blocks 49 removed and the second face of the slab filled, tamped solid, trowel finished, and despatched to a curing shed, the bed-plate is then turned, face up, and lowered to the discharging position where it receives a fresh volume of material for another slab, then the clamps 60 and 61 are unscrewed and the bed-plate, with its new load, dropped onto the base pillars and within the molding curb. Upon releasing the clamping members 60 position as shown by dotted lines in Figs. 1 and 6, where the bed slab and curing frame 63 are secured by means of screw clamps 6%, in this position the slab and its clamped parts are free to be turned and reversed by reason of the compensat weights being locked by the members 60 and 61, and while thus suspended the inclined conveyer, hereinafter more particularly described, is placed in position, but before the slab is lowered upon the conveyer the second face is fil ed, tamped solid, and trowel-finisaed. The conveyer comprises a pair of beams 65 having an inclined upper face provided with a plurality of wheels or rollers 66 for the and 61, tothe rails 67 of the track or curing frame 63, and each end of the beams has a depending pin 67 for engaging sockets 68 made through the cap plates and into the top of the pillars 1. Whenthe slab and its attachments are in position to be lowered onto the conveyer, the screw clamps having been removed, and the clamping members 60 and 61 unlocked, whereupon the slab is lowered, then the weights again raise the molding bed from the slab, and the clamping members 60 and 61 again operated are to hold the weights at a certain position as shown in Fig. 7 of the drawings, during turning or reversing the molding bed into position for lowering, by manipulating said members, for the next slab tamping.

The steps or procedure in handling a slab and its attachments is best illustrated in Figs. 5, 6 and 7, and it is preferable that the slabs be maintained in tilted or inclined position, to automatically convey them from the machine and in storing for aging and curing, and in connection herewith it should be remembered that the railed track and frame also acts as a curing frame because it remains with the slab during the setting stage of the curing or aging period.

The stanchions and their connections are grouped in two sets and constitute a two-- part frame having relative adjustment on the fixed rods M- and 25 with respect to the fixed pillars and posts. The molding bed curb or frame governs the adjustment of said two-part frame so that said adjustment is always centralized with respect to the fix-d pillars and posts for making slabs of various size. That is to say both sections of the two-part frame are slid outwardly on the rods in adjustment for making a large slab and said sections are slid inwardly in adjustment for making smaller slabs or flags, and said sliding and adjustments are made with respect to the curb frame after the latter has been secured and correctly adjusted to the pillars and the trunnioned yoke placed in position, then in making said adjustments the two parts of the main frame are brought up so that the cables wiljbe in vertical alinement with the yoke trunnions to w iich the ca lee are connected.

it will be seen that, with the exception of the pillars 1 and posts 18, the rods 14 and 25 afford means for sliding the parts connected therewith in adjustment for making slabs or flags of various size, that the curb-' frame 35 and its bed will predetermine said adjustment, that the bands which bind the stanchions and posts in clusters or sets insure unison movement of the stanchions and posts foradjustment, and that sheaves and weights are moved together by reason of said adiustment.

It will also be understood that the weights and the stanchion locks control the lifting as well as the raising and lowering movements of the slabs and their connected parts, that such weights are utilized according to the positions desired for the slabs, and that when the slabs are suspended by locking the weights, they are free to be revolved and -otherwise handled as desired or as occasion the machine as applied to a base plate upon which the posts and supports are slidable, obviously such plate may be omitted and the machine may be mounted on a suitable foundation having a smooth surface upon which said parts may he slid for adjustment. Other changes and mechanical equivalents may be made in the manufacture and practical working of the machine, and while I have shown the stanchions, rods and supporting posts as hollow or tubular to afford light weight in these parts, they may be of other suitable material.

Adverting to the balancing or counterweight device, the cables 56 work through a vertical tube extending from the cable heads 71. The weights 62 are carried by the disks 59 for raising and counterbalancing the molded flag and its bed, and after the curing frame is applied to the flag the weights 62 and 62 jointly counterbalance the flag, its curing frame and clamps 64s as shown in Fig. 6, then when the flag and its attachments are turned to reverse position and lowered upon the conveyer, the weights 62 raise the molding bed as shown in Fig. 7 of the drawings. By this arrangement and operation of the weights 62 and 62 separately and collectively and in connection with the clamping members 60 and 61, the mold and its attachments are manipulated separately and collectively as desired.

I do not wish to be understood as confining the invention in details of construction and connections, nor to the particular devices shown for holding the parts in ad justed position, but reserve the right to make such changes and variations in the machine and manner of connecting the parts thereof, as may not be inconsistent with the appended claims.
